Getting Started

1. Compile the code in Visual Studio.
2. Run the executable file (SpectrumAnalyzer.exe).
3. Import a dataset from a .csv file or excel spreadsheet using the button in the top right corner. Data must be organized in descending columns. This repo includes some sample datasets for testing.
4. Specify the units and any data pre-processing settings on the left side.
5. Click Compute FFT. Results will be displayed in the second tab.
6. All frequency components of the FFT will be shown on the left and in the lower plots. Selecting these components will overlay them onto the input dataset for comparison.
7. Reconstruction overlays can be stored by clicking the + button in the top right. Reconstruction data can be exported by right clicking on any stored value.
